Abstract (en)
[origin: EP0387471A2] The invention relates to an electrically controlled mixer faucet for cold and hot water, in which the control member determining the mixing ratio is moved by an electric motor (7). The purpose is to achieve temperature control which is for the user more convenient than earlier, and an initial temperature which is independent of the previous user. The control of the motor (7) is dependent on a target detected between a source of light (19) and a photocell (20) by the photocell (20). If the photocell (20) does not detect a user, the motor control circuit (13) receives its reference value from a circuit (18) the signal given by which has been set in advance. It is possible to produce by means of a suitable delay circuit (22) a certain delay before this signal is switched on. If there is a user in the detection field of the photocell (20), the control circuit (13) receives its control signal via the press-buttons (14, 15) used by the user and via corresponding circuit means (16, 17) which form control signals. The control circuit (13) receives a signal corresponding to the actual value of temperature via a temperature sensor (23) installed in the water mixing space.
